Fascinating article! I learned a new term from this article – Quantum Critical Point.
via A Quantum Pioneer Unlocks Matter’s Hidden Secrets – Scientific American
I followed one of the names mentioned in the article to find this short lecture on the topic.
A lingering question in my mind is about the energy consumed (be it in a cooling process, or in the application of high pressures, or in some other process) in creating these superconducting states and maintaining them for practical applications. Seems like that would be significant regardless of the efficiencies achieved once you get there. Is there not a trade-off involved? I do not remember any mention of this aspect in the article or the video.
